The shop worker added: "Of course it has affected me. We just don't feel safe in Europe anymore.

"I worried it was terrorism. I was glad when I found out it wasn't."

A Scotland Yard spokesman said: "Police were called at around 12:50pm today to reports of a man, reportedly armed with scissors, threatening passengers on a train bound for Tooting Broadway underground station.

"Officers, included armed officers, attend Tooting Broadway station and a search of the area was carried out but no-one matching the description of the man was found.

"Armed officers have been stood down, but local officers remain in the area."
